Emerging research is refining when paramedics can safely terminate resuscitation in children, with new evidence-based decision rules promising to standardise practices amid ongoing variability and complex cases.
Research into when resuscitation can be safely stopped in paediatric out-of-hospital cardiac arrest is starting to narrow a long-standing gap in emergency care, even though practice still varies widely. Pediatric arrests are uncommon but devastating, and survival remains poor overall, with infants doing particularly badly. A review in the National Library of Medicine found annual incidence and outcome data that underline the seriousness of the problem, while earlier epidemiological work showed that survival is strongly linked to factors such as witnessed collapse and bystander CPR.
That background helps explain why termination-of-resuscitation decisions in children have remained far more unsettled than in adults. Adult protocols are backed by clearer evidence and long-established rules, but many emergency medical services systems still lack equivalent guidance for children. In practice, that can leave crews and medical control physicians choosing between prolonged on-scene attempts and rapid transport, even when the chances of meaningful recovery appear remote.
The most important recent development is the move towards paediatric-specific decision rules. A Maryland consensus process produced proposed paediatric termination criteria that were later tested against a large national cohort and found to be highly specific for ruling out patients likely to achieve return of spontaneous circulation. Although that work focused on ROSC rather than long-term neurological recovery, it represented a significant step towards a more structured approach. More recent research has gone further by examining neurological outcome as the main endpoint.
A study from Japan reported that applying adult prehospital termination rules to children identified groups in which good neurological survival was exceedingly rare, particularly when the arrest was unwitnessed and no prehospital CPR had been started. That finding suggested adult-style criteria may have some value in paediatric cases, but it also raised questions about whether rules derived from adult populations are sufficiently tailored to children, especially in systems that rely on different response models.
The strongest paediatric-specific evidence so far comes from a 2024 analysis of more than 21,000 cases in the CARES registry. Researchers derived two clinical decision rules for non-traumatic paediatric out-of-hospital cardiac arrest: a four-factor rule aimed at predicting non-survival and a five-factor rule aimed at predicting non-survival or poor neurological outcome. Both showed very high specificity in the test dataset, although they still require external validation before widespread adoption. Even so, the emerging literature points towards a future in which EMS clinicians may have more evidence-based support for recognising futility, while still accounting for special situations such as drowning, electrocution, hypothermia and shockable rhythms.
